Abstract

A device can automatically open window/door after wind and rain, wherein a left and a right support with two bearings are mounted above a door frame; a feed screw is mounted in the two bearings; one end of the feed screw is fixed with a direct current speed reduction motor; a feed screw sleeve sheaths the feed screw and is mounted with a window/door connector for connecting a push-pull window/door; two lower ends of the feed screw are respectively mounted with a close stop switch and an open stop switch. After wind and rain, a recognition control circuit controls a relay to automatically open window/door to realize air circulation. The device is fit with a device which can automatically close window/door after wind and rain, and can be used to modify prior pull-push window/door.

Description

The wind and rain door gear of windowing automatically later

Affiliated technical field

The utility model relates to a kind of door gear of windowing, the particularly wind and rain door gear of windowing automatically later.

Background technology

During general family blowing and raining, lose for preventing that indoor article from getting wet, with manually window being shut, wind and rain is later again with manually opening window, as if in the family nobody, have to leave it to chance.

Summary of the invention

When overcoming blowing and raining, need the problem of manual control switch's window inconvenience, the utility model provides a kind of device, the door gear of windowing automatically after blowing and raining.

The technical scheme that its technical problem that solves the utility model adopts: above doorframe, two supports that tape spool holds about installation, screw mandrel is installed in the two bearings, one end of screw mandrel is fixed a DC speed-reducing, the screw mandrel cover is enclosed within on the screw mandrel, screw mandrel puts installs the window connector, connects door, and the close the door shutdown switch and the shutdown switch that opens the door are respectively installed in two ends below the screw mandrel.When motor rotated, screw mandrel rotated, and screw mandrel overlaps because of being fixed on the movable window, door is move left and right on guide rail just, and the sense of current of conversion motor, motor are also along with rotating, run into (or opening the door) shutdown switch of closing the door when lance (screw mandrel cover or window connector), just cut off motor power.What the control motor rotated is the wind and rain identification controller, and its operating principle is as follows: when blowing and raining, and the signal of wind and rain sensor, amplify through VT1, export to the capacitor C charging, if having only one or two signals through VT2, voltage on the capacitor can not make the VT3 conducting, and relay is not worked, if when a plurality of signals were imported, the voltage on the capacitor constantly raise, the VT3 conducting, relay is connected motor power, the shutdown switch of closing the door is run in the motor counter-rotating, the motor outage.Window is closed; After blowing and raining stops, the wind and rain sensor does not have signal to deliver to VT1, voltage on the capacitor C begins discharge through R4 VT3, and when the base voltage that is put into VT3 was lower than the conducting threshold values, relay discharged, relay is the relay of an amphinucleus point, motor just changes, and window is opened, and runs into the shutdown switch that opens the door, window has been opened in the motor outage.

The beneficial effects of the utility model are that after the blowing and raining, window can be opened automatically, ventilating air.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a present embodiment transmission mechanism structure chart.

Among the figure 1.Screw mandrel 2. screw mandrels overlap fixedly window 6. doors 7. shutdown switch 8. shutdown switch 9. DC speed-reducing 10. guide rails that open the door of closing the door of 3. window connectors, 4. bearings 5..

Specific implementation method

In Fig. 1, screw mandrel (1) two ends are installed in respectively on the bearing (4), screw mandrel one termination motor (9), screw mandrel cover (2) is enclosed within on the screw mandrel, fixed casement window gateway (3) is fixed on door (6), the appropriate location, both sides, below of screw mandrel (1), installation open the door shutdown switch (8) and the shutdown switch of closing the door (7), make lance with window connector (3) or screw mandrel cover (2), close behind the window with fixedly window (5) is airtight whole window, former guide rail (10) still keeps the smooth push-and-pull of door.Fig. 2 is the identification controller circuit theory diagrams, and its relay tip is electrically connected DC speed-reducing and power supply.Fig. 3 is an amphinucleus point relay control motor positive and inverse schematic diagram, and wherein (7) are the shutdown switches of closing the door, and (8) are the shutdown switches that opens the door.

Claims

1. the wind and rain door gear of windowing automatically later, above doorframe, two supports that tape spool holds about installation, screw mandrel is installed in the two bearings, screw mandrel one end is fixed a DC speed-reducing, the screw mandrel cover is enclosed within on the screw mandrel, screw mandrel puts installs the window connector, connect door, the close the door shutdown switch and the shutdown switch that opens the door are respectively installed in two ends below the screw mandrel, and it is characterized in that: the two ends of screw mandrel are installed bearing and support respectively, and an end of screw mandrel is a DC speed-reducing, the screw mandrel cover is enclosed within on the screw mandrel, connects screw mandrel cover and door with the window connector.

2. the feature according to the door gear of windowing automatically after the right 1 described wind and rain is: respectively there are the close the door shutdown switch and the shutdown switch that opens the door in both sides below the screw mandrel, and relay is the relay of an amphinucleus point.
